Hi everyone,

could you consider applying this patch so that we are able to build rt
kernel for genericx86(-64)?

Best regards

Send a patch against the main linux-yocto-rt recipe (not via this
attached bbappend
patch), and we can have a look.

But adding the support is something that you can easily carry in your
own layer,
since by adding the support to the main recipe, we are implicitly agreeing that
I'll build and boot test it with each update. And I don't have a large
objection to that,
but I add new supported boards with caution, in particular genericx86, since it
doesn't have a tightly controlled platform or set of drivers.

Cheers,

Bruce

Bruce, the genericx86 BSPs are not in oe-core, they are in
meta-yocto-bsp, so the bbappend is the right place to do this.

For context, I met with Eric and suggested he send this patch. I would
be adding it myself if he didn't as genericx86* absolutely must support
PREEMPT_RT IMNSHO.

Ah yes. Right you are.

Then I assume you'll be taking all the testing of it as well ? The
patch as it stands is still not properly formatted, but that's a
minor 'nit.

We should have cc'd the poky list on this as well, since it actually
isn't any changes to linux-yocto itself to support the type.

Yes, this needs to be part of our QA.

Eric, please have a look at the docs on
create-pull-request/send-pull-request or just using "git send-email" to
get your patches out in the appropriate format.

Indeed it should have been. Takes some experience to get things to the
right list :-)
